Of course, the original TO-3 regulators were linear and would ... surely has a wider input voltage range and more output current capacity. We’ve seen replacement switching regulators before ...

In fact, this is their main advantage over switching converters, where noise isolation and emissions are major system concerns. The fundamental concept of the linear voltage regulator is shown in ...

but the linked video also has him using the modules to repair a Commodore 1541 which originally had the linear TO3 voltage regulators. It’s definitely a non-trivial task to build a switching ...

Nexperia has introduced an inductor-less energy harvesting IC that is able to cold start with 12μW from 270mV. Called ...
